10 Celebrity Catfights

After Kelly Osbourne (left) made some unkind comments about former friend Christina Aguilera, Aguilera struck back. "She must have a crush on me because every five minutes she's saying something about me," Aguilera told Q Magazine. "I did see her at a club and said, 'Look, what is your problem?' And she had nothing to say. If you're going to talk sh** about me, do it to my face, because if you don't back it up you're just talking out of your ass." Classy.

Lindsay Lohan was widely reported to have written "Scarlett is a c***" on a bathroom wall. She then followed that up with this diatribe to Interview Magazine. "What hurts me the most is that I work just as hard as any other actress around my age, like Scarlett Johansson, but I just don't get the opportunities that they get because people are so distracted by the mess that I created in my life." Scarlett has maintained she has only met Lohan in passing, and does not know what may have stoked the actress' anger. So, so far, this catfight is a bit one-sided.

Jessica Simpson (left) dates Dallas Cowboys quarterback Tony Romo, but Carrie Underwood used to. When Underwood told Allure Magazine that Romo stilled called her, Simpson took offense. Simpson later blamed the press. "It's definitely media-driven. People are just trying to make a story out of nothing," Simpson said. "I respect her and hopefully she respects me. We've just dated the same guy - that's it!"

Jenny McCarthy has an autistic son, and is against childhood vaccines because she thinks the shots and her son's impairment are related. Amanda Peet is the spokesperson for Every Child By Two, which wants all kids vaccinated by age two. Peet called anti-vaccine parents like McCarthy "parasites." McCarthy responded, saying, "I am so proud to be a 'parasite.'" Peet backtracked on the use of the word "parasite," but the damage was done.

Jennifer Aniston and Angelina Jolie's distaste for one another has been so well-chronicled, the Associated Press has created this graphic, which resembles a boxing match poster, and made itavailable for any AP subscriber writing a story about the two.

Paris Hilton (left) and Nicole Richie were best friends when they started filming "The Simple Life" together. By Season 3, they hated each others' guts, and the show had to switch gears and film them separately. Today, they are polite to one another, but their BFF days are over.

Rosie O'Donnell (left) and Elizabeth Hasselbeck (far right) clashed on "The View" for over a year, propelling the show to its highest ratings ever. O'Donnell couldn't take the heat, however, and quit, making Hasselbeck the winner by TKO.

Not all catfights in Hollywood are what they seem. Alexis and Krystle Carrington were warring characters of the 1980s hit "Dynasty," whose physical confrontations became the stuff of TV legend. But the actresses who played them, Joan Collins (right) and Linda Evans, were quite friendly, and reappeared together in a 2006 reunion special called "Dyansty: Catfights and Caviar."
